String splitting

Question

Say I have a string a such:

String str = "Kellogs Conflakes_$1.20";

How do I get the preceding values before the dollar ($) sign.

N.B: The prices could be varied say $1200.

Answer 1

You can return the substring using substring and the index of the $ character.

str = str.substring(0, str.indexOf('$'));

Answer 2

You could use String.split(String s) which creates a String[].

String str = "Kellogs Conflakes_$1.20";              //Kellogs Conflakes_$1.20
String beforeDollarSign = String.split("$").get(0);  //Kellogs Conflakes_

This will split the String str into a String[], and then gets the first element of that array.

Answer 3

Just do this for split str.split("$") and store it on an array of String.

String[] split = str.split("$");

And then get the first position of the array to get the values that you have before the $

System.out.println(split[0]); //Kellogs Conflakes_

At the position 1 you will have the rest of the line:

System.out.println(split[1]); //1.20

Answer 4

Try this:

public static void main(String[] args) {

String str = "Kellogs Conflakes_$1.20";

String[] abc=str.split("\ \$");

for(String i:abc)

{
    System.out.println(i);
}

}

after this you can easily get abc[0]
